Guys,
With the Dodd amps I recently purchased, the seller gave me two quads of JJ EL-34 tubes in addition to the SED EL-34's. However, he told me that two out of the 8 JJ tubes are bad and he doesn't know which two are bad.
I don't want to play around with bad tubes in the amp trying different combinations to identify the non-working ones.
Is there anybody out there who has a tube tester that would be willing to identify the bad tubes?
Thanks,
George
